Bug 640 – Strage error messages around structInstance.init

// credit goes to http://pc8.2ch.net/test/read.cgi/tech/1158013550/956 struct A { int a; } void main() { A x; // <-- test.d(3) x = x.init; } ---------------- test.d(3): Error: cannot implicitly convert expression (0) of type int to A test.d(3): Error: cannot cast int to A If x=x.init is commented out, or changed to x=A.init, the error disappears. Even worse, a slightly modified version crashes dmd (access violation). struct A { int a; } void main() { A x = {0}; x = x.init; }

The spec introduced at D 2.001/1.017 > The .init property for a variable is now based on its type, not its initializer. fixed this problem.
